“We were not well protected,” Fehn said. “We feel we are in a better position than we were before.”

Even so, the identity of the individual(s) responsible for the attacks remains unclear.

Shortly after the April attack, a hacker named Exodus claimed responsibility for the outage, alleging that he was paid $500 in Bitcoin by a client with a grudge against Rutgers to disrupt the university’s computer systems.

Exodus has since taunted Rutgers students and officials on both Reddit and Pastebin, and he has shared his thoughts on the university’s outages in an interview with a tech blogger. However, it is nevertheless uncertain whether Exodus is responsible for any or all of the four targeted attacks Rutgers suffered during the 2014-2015 academic year or whether he is just a hoax.

The Federal Bureau of Investigations, which assisted Rutgers following the targeted attack back in April, has not responded to requests to comment on its ongoing investigation of the incident.
